TECHNICAL FIELD

The present invention relates to a novel pyrimidine derivative, morespecifically to a 2,4,6-substituted pyrimidine derivative. The presentinvention has an action of inhibiting the growth of Plasmodium speciesand thus can be useful for the treatment, prevention and/or inhibitionof propagation of Plasmodium infection.

BACKGROUND ART

Malaria is a protozoan infection widely distributed in tropical tosubtropical regions. About 80% of the patients with malaria is infectedwith Plasmodium falciparum, a Plasmodium species parasitic on humans,and this is a very dangerous infection causing death in serious cases.Furthermore, due to recent global warming, malaria is not only endemicin developing countries in tropical and subtropical regions but alsoseems to be spreading in developed countries in temperate regions.

For Plasmodium species parasitic on humans, chloroquine and fansidar (adrug combination of pyrimethamine and sulfadoxin), which are called atraditional drug and were developed in the 1930s to the 1960s, have beenused. Later, artemisinin derivatives, an active ingredient of Artemisiaannua, a herbal drug, was developed after the 1980s, and have been used.

However, Plasmodium resistant to chloroquine and/or fansidar andPlasmodium resistant to a multidrug containing those have emerged. Thereis also a report on the emergence of protozoa resistant even toartemisinin derivatives which was developed later.

In response to the emergence of such protozoa resistant to existingdrugs, antimalarials effective for Plasmodium species have beendeveloped worldwide. However, in the development of antimalarials, inmany cases the antimalarial activity identified in vitro cannot beidentified in vivo, or drugs are found to be toxic, and thus few drugshave been found to be effective for drug-resistant strains and haveantimalarial activity in vivo.

Heretofore 2,4,5-substituted pyrimidine derivatives (Non patent document1 and Patent document 1) and 2,4,6-substituted pyrimidine derivatives(Non patent document 2) have been reported as a substance havingantimalarial activity, but no compounds are known to have the structureof the compound of the present invention.

Test Example 1: In Vitro Antimalarial Assay

For the evaluation of the antimalarial activity of the compound of thepresent invention, K1 strain, a drug resistant strain of Plasmodiumfalciparum, and FCR3 strain, a drug sensitive strain thereof, which weregenerous gift from Professor Kiyoshi Kita of the Graduate School ofMedicine and Faculty of Medicine, the University of Tokyo, were used tomeasure the in vitro antimalarial activity of the compound against thosePlasmodium species according to the method established by Otoguro et al.(Otoguro, K., Kohana, A., Manabe, C., Ishiyama, A., Ui, H., Shiomi, K.,Yamada, H. & Omura, S.: Potent antimalarial activity of polyetherantibiotic, X-206. J. Antibiot., 54: 658-663, (2001)).

The parasites were grown based on a slightly modified method from theoriginal method reported by Trager and Jensen (Trager, W. and Jensen,J.: Human malaria parasites in continuous culture, Science, 193:673-677, (1976)), and those which were maintained and sub-cultured bythe method were used. More specifically, in a culture dish, erythrocytesinfected with the protozoa, which had been sub-cultured using a RPMI1640 medium to which 10% human plasma had been added and fresh humanerythrocytes, were diluted (hematocrit value: 2 to 5%, parasitaemia:0.25 to 1%), and were cultured at 37° C. in a mixed gas of 3% O₂-4%CO₂-93% N₂, and continuously cultured while changing the medium andadding fresh erythrocytes at 2- or 3-day intervals.

A drug susceptibility test was performed by modifying the methodestablished by Desjardins et al. (Desjardins, R. E., Canfield, C. J.,Haynes, D. E. and Chulay, J. D.: Quantitative assessment of antimalarialactivity in vitro by a semiautomated microdilution technique.Antimicrob. Agents Chemother., 16: 710-718 (1979)). More specifically,190 μL of a suspension of protozoa which had been precultured(hematocrit value: 2%, parasitaemia: 0.5 or 1%) and 10 μL of a solutionof a test compound (5% DMSO solution) serially diluted so that the finalconcentration was 12.5 to 0.0001 μM were put in each well of a 96-wellplate, and after mixing, the same was cultured for 72 hours in the abovemixed gas.

For the measurement of the growth of protozoa, the method established byMakler (Makler, M. T., Rise, J. M., Williams, J. A., Bancroft, J. E.,Piper, R. C., Gibbins, B. L. and Hinrichs, D. J.: Parasite lactatedehydrogenase as an Assay for Plasmodium falciparum drug sensitivity,Am. J. Med. Hyg., 48: 739-741 (1993)) was modified to colorimetricallydetermine parasite lactate dehydrogenase (p-LDH) using Malstat reagent(Flow Inc., USA).

More specifically, 72 hours after the culture, the 96-well plate wasdirectly frozen at −20° C. for 18 hours and melted at 37° C. to hemolyzethe protozoan-infected erythrocytes and destroy the protozoa to preparea crude enzyme solution. 100 μL of Malstat reagent and 20 μL of thecrude enzyme solution were added to and mixed in each well of another96-well plate, and after reacting for 15 minutes at room temperature, 20μL of a nitroblue tetrazolium 2 mg/mL phenazine ethosulfate 0.1mg/mL=1:1 solution was added to the respective wells, and reaction wasperformed in dark conditions at room temperature for 2 hours.

The absorbance of the blue formazan product formed by the reaction wasmeasured at a measurement wavelength of 655 nm by using a microplatereader (Labsystems, Finland) to colorimetrically determine the growth ofthe protozoa. The 50% growth inhibitory concentration for the protozoaof the compound (IC₅₀ value) was determined based on theconcentration-response curve of the compound.

The compounds of the present invention showed a similarly highantimalarial activity for both the drug resistant strain, K1 strain, andthe drug sensitive FCR strain. The results show that the compounds ofthe present invention have excellent efficacy for inhibiting the growthof Plasmodium species.

Test Example 2: In Vivo Antimalarial Assay

In vivo antimalarial activity of the compound of the present inventionwas determined using a mouse model infected with rodent malaria P.berghei N strain (drug sensitive strain) by slightly modifying themethod described in the above publication of Otoguro et al. (2001) andthe method reported by Peters et al. (Peters, W., Portus, J. H. andRobinson, B. L.: The chemotherapy of rodent malaria. XXII. The value ofdrug-resistant strains of P. berghei in Screening for bloodschizonticidal activity. Ann. Trop. Med. Parasitol., 69: 155-171,(1975)). The P. berghei N strain was generous gift from Dr. W. Peters(Northwick Park Institute for Medical Research, Middlesex, UnitedKingdom).

A group of three ICR male mice (Charles River Laboratories Japan, Inc.)weighing 18 to 20 g was used as a test animal. Using protozoa maintainedand sub-cultured by in vivo passage, 2×10⁶ parasite-infectederythrocytes were pre pared, and the mice were infected therewith bytail vein injection. For the therapeutic test, a 1-day suppressive testwas performed. The day of infection was defined as day 0. Two hoursafter the infection, a solution of the test compound (solvent: 3%DMSO/0.5% methylcellulose400-solution or suspension) was administeredintraperitoneally (i.p.) once to 3 times. On day 4, blood smearpreparation was prepared by collecting from the tail vein and the ratioof parasite-infected erythrocytes (parasitaemia) was investigated todetermine the therapeutic effect (inhibition percentage) based on theinfection rate of the group to which the compound was not administered.The significance test was performed by Dunnett's test.

In vivo antimalarial activities of representative compounds of thepresent invention are shown in Table 4.

The compounds of the present invention significantly suppressed theparasitaemia with 50% inhibition in a mouse model infected with rodentmalaria P. berghei N strain compared with the vehicle control group wheninjected i.p. at 3 or 10 mg/kg once or twice, showing therapeuticeffect. The results suggest that the effective dose 50 (ED₅₀) of thecompounds of the present invention is about 3 to 10 mg/kg, indicatingthe compounds have excellent efficacy as a therapeutic agent forplasmodium infection at low doses.

INDUSTRIAL APPLICABILITY

The compound of the present invention is useful as an agent fortreating, preventing and/or inhibiting propagation of infection withhuman infectious Plasmodium such as Plasmodium falciparum, Plasmodiumvivax, Plasmodium malariae, Plasmodium ovale and Plasmodium knowlesi.The compound of the present invention is also useful for treating,preventing and inhibiting propagation of infection with Plasmodiumresistant to existing antimalarials such as chloroquine and fansidar.The compound may also be used as an agent for inhibiting growth ofPlasmodium in the form of a reagent for experiment and research.
